Depth color light penetration you tell

Description:
Factors such as phytoplankton and zooplankton suspended in the water, along with sediment such as sand or mud all affect light penetration and affect which colors get absorbed; this does not mean that other wavelengths are affected negatively. The most common factor that changes the penetration depth of light in water is the amount of light available; a simple principle, if it’s cloudy and dark there is less light .

The colored curves on the graph above show the intensity of light (solar radiation) at different depths in the ocean plotted against wavelength of light at each depth. The colors indicate light intensity at four water depths: 0 meters meter = slightly less than a half inch meters=20 inches meters= feet. Light absorption in the sea reduces the amount of visible light rapidly with depth.
